Ok to sum it up i have been having a hell of a time with my new 306 i dropped it in 2 weekends ago and i stil have yet to enjoy it , due to various issues, well one is this Vac leak i have a flucuating needle from 8in to 12 in of vac so first i checked the obvious with some brake clean to my intake gaskets and the motor jumped when i sprayed around it so i replaced the intake gaskets and while i was in there i re adj my scorpion 1.6 stud mount ( alum head , hyd roller ) cuz they were making to much noise and poss thinking that a valve was slightly hanging open cuz of an over tight issue( is that poss ? )( i followed the adj procedure perfectly so i put all back together and started it and wouldnt you know it my Vac is still the same (fluc and still 8-13in )(i installed new ford lifters and i did soak in trans fluid and prime the motor ) and my rockers are still making noise so now im in the process of tightening them while the motor is running and they dont seem to be geting any quieter ,i have only done bank 2 so far and im in the process of doin bank one ...If it was a valve / lifter issue , would i be able to see which lifter/ valve it is with my vac gauge hooked up and running and loosen the rocker arm to eliminate the valve and my vac should rise . Also while pulling the upper intake off i noticed the CYL 's 8-7-5 from upper to lower was wet with gas and oil mixed . why only these cyl's? , ( 73mm C&L maf , 24lb inj , 70mm accufab tb , 190lph ) all other intake runners are dry ..what caused this , any ideas or responses are appreciated ...thanks fellas !!!!!!!
